Multiple unspecified vulnerabilities in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allow remote attackers to execute arbitrary code by instantiating certain COM objects from Wmm2fxa.dll as ActiveX controls including (1) DXImageTransform.Microsoft.MMSpecialEffect1Input, (2) DXImageTransform.Microsoft.MMSpecialEffect1Input.1, (3) DXImageTransform.Microsoft.MMSpecialEffect2Inputs, (4) DXImageTransform.Microsoft.MMSpecialEffect2Inputs.1, (5) DXImageTransform.Microsoft.MMSpecialEffectInplace1Input, and (6) DXImageTransform.Microsoft.MMSpecialEffectInplace1Input.1, which causes memory corruption during garbage collection.

Unspecified vulnerability in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allows remote attackers to execute arbitrary code via "unexpected data" related to "parameter validation" in the DXImageTransform.Microsoft.Light ActiveX control, which causes Internet Explorer to crash in a way that enables the code execution.

Unspecified vulnerability in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allows user-assisted remote attackers to execute arbitrary code via a crafted web page that triggers memory corruption when it is saved as a multipart HTML (.mht) file.

Microsoft Internet Explorer before Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1, when Prompt is configured in Security Settings, uses modal dialogs to verify that a user wishes to run an ActiveX control or perform other risky actions, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking an object or pressing keys that are actually applied to a "Yes" approval for executing the control.

Microsoft Internet Explorer 5.01 through 6 does not always return the correct IOleClientSite information when dynamically creating an embedded object, which could cause Internet Explorer to run the object in the wrong security context or zone, and allow remote attackers to execute arbitrary code.

Microsoft Internet Explorer 5.01 through 6 allows remote attackers to execute arbitrary code via by instantiating the (1) Mdt2gddr.dll, (2) Mdt2dd.dll, and (3) Mdt2gddo.dll COM objects as ActiveX controls, which leads to memory corruption.

Microsoft Internet Explorer 5.01 through 6 does not always correctly identify the domain that is associated with a browser window, which allows remote attackers to obtain sensitive cross-domain information and spoof sites by running script after the user has navigated to another site.

Microsoft Internet Explorer 5.01 through 6 allows remote attackers to conduct phishing attacks by spoofing the address bar and other parts of the trust UI via unknown methods that allow "window content to persist" after the user has navigated to another site, aka the "Address Bar Spoofing Vulnerability." NOTE: this is a different vulnerability than CVE-2006-1626.

Unspecified vulnerability in Microsoft Internet Explorer 5.01 through 6 allows remote attackers to execute arbitrary code via certain invalid HTML that causes memory corruption.

Buffer overflow in URLMON.DLL in Microsoft Internet Explorer 5.01 through 6 allows remote attackers to execute arbitrary code via a crafted URL with an International Domain Name (IDN) using double-byte character sets (DBCS), aka the "Double Byte Character Parsing Memory Corruption Vulnerability."
